Luxardo cherries are a type of cocktail cherry that are a premium cocktail garnish. These cherries are made from Marasca cherries that are steeped in a syrup made from their own juice and sugar, which gives them a sweet and sour taste. They are then preserved in a thick, dark syrup made from Marasca cherry juice. Luxardo cherries are prized for their rich flavor and deep red color, and are often used to garnish cocktails such as Manhattans, Old Fashioneds, and other classic drinks.
